Player help
Most problems can be fixed without losing progress. Back up your save code before clearing browser data or changing devices.
Return to the game
Reload the page, disable aggressive script blockers for this site, and use a current version of Chrome, Edge, Firefox or Safari. Private browsing may restrict storage and service-worker behavior.
Open Settings and download a JSON backup or copy the save code before troubleshooting. Keep your Cloud Sync ID private; it acts like a password. The local save remains separate from the cloud copy.
Browsers require a click, key press or controller action before audio can begin. Check the music and sound sliders in Settings and confirm the browser tab is not muted.
Connect the controller before starting the game, press a button, and confirm Gamepad input is enabled in Settings. Wired or officially supported Bluetooth controllers are the most reliable.
Try again on a different network and confirm both players use the current release. Strict corporate networks and some mobile carriers may require the configured TURN relay.
Third-party units load only after advertising consent. Ad blockers, regional inventory, network filtering or declined consent can make optional ad-funded rewards unavailable without blocking normal play.
